2 Building Simple Models with SimEvents Software

2-30

• Use discrete events to update signals that influence time-based dynamics.

• Adjust parameters in the discrete-event system to affect the results of the overall

hybrid model.

Note: A more realistic way to represent a distributed control system is to model

communication over a shared network, where time delays and transmission failures

might depend on network traffic from other distributed components. The Effects of

Communication Delays on an ABS Control System example shows the behavior of the

ABS system when distributed components communicate over a more complex Control

Area Network (CAN) bus.

Lesson 1: Run the Time-Based Model

This lesson examines the performance of the existing ABS model. In this version of the

model, which contains only Simulink blocks, there is no communication delay between

components of the ABS.

Open the existing ABS model by clicking abs_timebased.

The model contains the following subsystem blocks that together form a completed

closed-loop model of an ABS:

• Desired Relative Slip block that provides a setpoint to the controller.
